ABSTRACT:
A security device and system for preventing unauthorized access to and operation of fire hydrants. The security device includes a first end portion for coupling the device to a portion of a fire hydrant. The first end portion preferably is coupled to the hydrant by clamping it between an outlet port of the hydrant and a cap for covering the outlet port. A second end portion covers a valve control device of the hydrant to control access to the valve control device and thereby prevent unauthorized persons from activating it. An intermediate portion integral with the first and second end portions extends vertically from the first end portion to the second end portion. The system for preventing unauthorized operation of a fire hydrant includes the security device described above, a bonnet for protecting a valve control device of the hydrant, and a locking cap for closing an outlet port of the hydrant. The system also may include a tool for removing the locking cap from the outlet port and for opening the valve control device.
